The volume of 10% is $= 50$cc and the volume of 4% is $= 100$cc

Explanation:

Let the volume of 10% acid be $= x$cc

Then, the volume of 4%# acid is $\left(150 - x\right)$cc

Then,

$x \cdot 10 + \left(150 - x\right) \cdot 4 = 150 \cdot 6$

$10 x + 600 - 4 x = 900$

$6 x = 900 - 600 = 300$

$x = 50$cc

and

$150 - x = 100$cc
